A daily Arabic root جذر

Three letters. A whole family of words.

A two-minute daily puzzle for Qur'an readers.

Most Arabic words are built on a root, usually three consonants. Find the root, watch its word family appear, then meet it in an āyah.

The root

صṣ بb رr

ṣ–b–r

patience · endurance · steadfastness

  1. صَبْر ṣabr patience
  2. صَابِر ṣābir steadfast
  3. صَبُور ṣabūr enduring
  4. اِصْبِرْ iṣbir “be patient!”

The letters stayed. Everything else moved.

How it plays

A few short steps, and you are done for the day.

No lives, no energy bar, no reason to come back twice. It ends where it should end.

01

Hunt

You are shown a few related words: different shapes, related meanings. Three consonants run through all of them. Find what repeats.

The Hunt screen: a word family — ṣabr, ṣābir, ṣābirīn — above a pool of Arabic letters and three empty radical slots.

02

Bloom

The root you found lights up inside every word it made. Patience, the patient one, endurance, the command to endure — one skeleton, wearing different clothes.

The Bloom screen: the three radicals as coloured tiles, and the same three colours visible inside each derived word.

03

The āyah

Then you meet the root in an āyah where it appears, in Uthmani script, with Pickthall's translation. It is the reason Jadhr exists.

The root you just found, in an āyah where it appears

فَٱصْبِرْ صَبْرًا جَمِيلًا

“But be patient (O Muhammad) with a patience fair to see.”

Sūrat al-Maʿārij 70:5 · Pickthall

04

Spot

Last, you find the three root letters yourself in one word from that āyah, written in simple spelling. Then you are done. On later days a short Echo comes first: a root you met before returns as one quick question, so it stays with you.

Why a root and not a word

A mechanic only Arabic can have.

English word games guess spellings. Arabic has something else underneath its vocabulary: a system of roots. Learn one root and you start recognising its relatives. It is a head start, not a shortcut.

The grid of tiles is the easy part. What makes Jadhr worth opening is the content underneath it: authored roots, real word families, and every āyah machine-checked word by word against the Tanzil text and the Quranic Arabic Corpus, and chosen against published criteria.

67%

of the rooted word occurrences in the Qur'an come from the 230 roots in Jadhr so far (33,567 of 50,269). Seeing a root is not the same as understanding a verse, but it is a start you can count.

18

semantic fields, from Mercy and Light to Struggle and Dominion, so the roots you hold form a map rather than a list.

840

word forms, each mapped to the root letters inside it.

Thirty days

A root for every day of Ramadan.

Written down before launch, so it can be held against us

What Jadhr will never sell you.

Every one of these is a normal, profitable thing that daily games do. They are ruled out in the product spec, not in a blog post, because a Qur'anic word should never be the thing standing between you and a payment screen.

  • Never an extra guess for money. The limit is the game. Selling relief from it is selling frustration.
  • Never a paywall on the Bloom. Miss the root and you still learn it. The teaching is not the prize.
  • Never a paid hint you need. Support that learning requires is part of learning.
  • Never lives, energy or a price on a missed day. Miss a day and nothing was taken from you.
  • Never an ad beside a verse. No advertising anywhere near Qur'anic text. Not a banner, not an interstitial.
  • Never your data as the product. The Daily works on your device, and your record of what you know is yours. No account, no ads, no tracking scripts.

If Jadhr ever earns, it earns from tools for teachers, classes and masājid — the people who want more than one root a day — while the daily puzzle stays whole and free for everyone else.

Where it honestly is

Playable, young, and not pretending otherwise.

The app is real and runs end to end. Every āyah is machine-checked word by word against the Tanzil text and the Quranic Arabic Corpus, every cited word is confirmed to carry its root, transliteration is generated under one declared scheme rather than typed by hand, and each āyah is chosen against published criteria. No one has given it a scholarly review, and we do not claim one. If you see a mistake, tell us and we will fix it. Reverence over speed.
